The phrase "Advances in technology meant astronomy in navigation became redundant," made me reflect.
I used to enjoy taking stars and got a great sense of achievement especially if we had been "lost" for a few days.

I am totally out of touch having left the sea over 12 years ago when satnav was in its infancy and some old men still wanted astro navigation as a check. Can someone please tell me what the position finding routine is on a modern ocean going ship now and what back ups are in place.

There are several threads that cover the subject. Just do a forum search on the word sextant.
Here's one to get you started

There are usually 3 or 4 different independent gps units on the bridge of a modern deep sea vessel but astro nav is still done where possible or practicable though in cases of very low manning it may not be practicable.
